COMBINED PUNCHI NG AND SHEARING MACHINE.

SPECIFICATION forming part of Letters Patent No. 365,490, dated June 28, 1887.

Application filed November 3, 1886. Serial No. 217.905. (X0 model.)

To all whom, it may concern.-

Be it known that I, NICHOLAS J. Bron, of Meadville, Crawford county, Pennsylvania, have invented aCompound Punch and Shears, of which the following is a specification.

The invention will first be described in connection with the drawings, and then pointed out in the claims.

Figure 1 of the drawings is a side elevation, and Fig. 2' a vertical section. V

In the drawings,.A represents the supporting-frame whioh carries thefixed shear F and,

on a pivot, the movable shear G, pivoted at 1.

The rear end of shearG is connected, by a pivgle-spurred cam L and the double-spurred cam M, which has a bearing, It, in the frame. Hence the punchI is actuated by two separatetrains of mechanism, giving great leverage, while the shears are worked simultaneously.

K is the apertured die used with the punch, and S the gage which I preferably employ.

What I claim as new, and desire to protect by Letters Patent, is

1. The mechanism 0 D E,combined with the mechanism M L, to operate the punch, as described.

2. The combination, with the lever O and shear G, of the mechanism D E H, of which the lever E is pivoted in the movable punch I, as and for the purpose specified.

NICHOLAS J. RICE.
